the area of the shaded region would be CD=5
Since,
ABC is an triangle with height 6cm and base 9cm So , Area of triangle ABC=1/2×h×b
=9×3
=27 sq. cm
since,
FGH is an equilateral triangle
Area of equilateral triangle=√3/4×a×a
=10.81 sq. cm
since,
BCDG is an Rectangle
Area of Rectangle=length×breadth
=9×18. ......(26cm-8cm)
=162sq cm
since,
GEFH is an rectangle (l=8cm,b=5cm)
Area of rectangle=l×b
=8×5
=40 sq. cm
Area of shaded region = Sum of all the area
=(27+10.81+162+40)=239.81 sq. cm Answer
